Sehun wants to throw himself off a building. For loving his best friend's ugly smiling crinkled face. For loving his best friend's soft blonde locks so much so that he desires to ruffle it roughly. 

As most of it, for being a coward not to confess.

And now, great, when his best friend, Luhan signs him up to be a fake couple to win the prize money for Luhan's air tickets and accomodation at Brazil to watch the world cup, he wants to throw himself off the building for not being able to say 'no' .
